It might silently break a lot of stuff. There's about 6 ways to reset a
machine (probably more) and it's not always trivial to see why a certain
reset method is needed at a certain time.

To your patch, I don't understand why you're suggesting to rename
hard_reset to board_name_hard_reset(). That seems like an awful idea...
Any reason for it?
